ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     In accordance with Section 145 of the General Corporation Law of the State
of Delaware, Article VII of the Company's Third Amended and Restated Certificate
of Incorporation provides that no director of the Company shall be personally
liable to the Company or its stockholders for monetary damages for breach of
fiduciary duty as a director, except for liability (i) for any breach of the
director's duty of loyalty to the Company or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) in respect of certain unlawful dividend payments or
stock redemptions or repurchases, or (iv) for any transaction from which the
director derived an improper personal benefit. In addition, the Certificate
provides that if the Delaware General Corporation Law is amended to authorize
the further elimination or limitation of the liability of directors, then the
liability of a director of the Corporation shall be eliminated or limited to the
fullest extent permitted by the Delaware General Corporation Law, as so amended.
 
     Article V of the Company's Amended and Restated By-laws provides for
indemnification by the Company of its directors, officers and certain
non-officer employees under certain circumstances against expenses (including
attorneys fees, judgments, fines and amounts paid in settlement) reasonably
incurred in connection with the defense or settlement of any threatened, pending
or completed legal proceeding in which any such person is involved by reason of
the fact that such person is or was an officer or employee of the Company if
such person acted in good faith and in a manner he or she reasonably believed to
be in or not opposed to the best interests of the Company, and, with respect to
criminal actions or proceedings, if such person had no reasonable cause to
believe his or her conduct was unlawful.
 
     Under Section 8(b) of each of the Underwriting Agreements filed as Exhibit
1.1 and Exhibit 1.2 hereto, the U.S. Underwriters and the International
Underwriters have agreed to indemnify, under certain conditions, the Company,
its directors, certain officers and persons who control the Company within the
meaning of the Securities Act of 1933 against certain liabilities.

ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES
 
     During the past three years, the Company has issued unregistered securities
to a limited number of persons, as described below. No underwriters or
underwriting discounts or commissions were involved. There was no public
offering in any such transaction, and the Company believes that each transaction
was exempt from the registration requirements of the Securities Act of 1933, as
amended (the "Securities Act"), by reason of Section 4(2) thereof, based on the
private nature of the transactions and the financial sophistication of the
purchasers, all of whom had access to complete information concerning the
Company and acquired the securities for investment and not with a view to the
distribution thereof. In addition, the Company believes that the transactions
described in paragraphs (4), (5) and (7) below were exempt from the registration
requirements of the Securities Act, by reason of Rule 701 thereunder.

ITEM 17.  UNDERTAKINGS
 
     The undersigned registrant hereby undertakes to provide to the Underwriters
at the closing specified in the Underwriting Agreements certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
 
                                      II-5

     The undersigned registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of the Registration Statement in reliance upon Rule 430A and contained in a
     form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     Registration Statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.
